1600  *
1601  * Win95:
1602  * - if the buffer is 0 or 1 character long then it is as if it was of
1603  *   infinite length.
1604  * - otherwise, if the buffer is too small only the section names that fit
1605  *   are returned.
1606  * - note that this means if the buffer was too small to return even just
1607  *   the first section name then a single '\0' will be returned.
1608  * - the return value is the number of characters written in the buffer,
1609  *   except if the buffer was too small in which case len-2 is returned
1610  *
1611  * Win2000:
1612  * - if the buffer is 0, 1 or 2 characters long then it is filled with
1613  *   '\0' and the return value is 0
1614  * - otherwise if the buffer is too small then the first section name that
1615  *   does not fit is truncated so that the string list can be terminated
1616  *   correctly (double '\0')
1617  * - the return value is the number of characters written in the buffer
1618  *   except for the trailing '\0'. If the buffer is too small, then the
1619  *   return value is len-2
1620  * - Win2000 has a bug that triggers when the section names and the
1621  *   trailing '\0' fit exactly in the buffer. In that case the trailing
1622  *   '\0' is missing.
1623  *
1624  * Wine implements the observed Win2000 behavior (except for the bug).
1625  *
1626  * Note that when the buffer is big enough then the return value may be any
1627  * value between 1 and len-1 (or len in Win95), including len-2.
